Large HD Driver
The large 40 millimeter HD driver combined with a copper-clad aluminum wire (CCAW) voice coil and neodymium magnets built into the HRM-7 produce outstanding audio playback and great sound localization. The new HD driver along with its strong magnet structure can reproduce a very wide frequency response from 5 Hz to 40 kHz, ideal for all types of music listening including high-resolution audio files.
Dual Chamber Bass Reflex Enclosure
Pioneer developed a dual chamber bass reflex enclosure to enable the headphones to generate lower bass frequencies while still maintaining great control of the HD driver for increased audio accuracy. The sound isolating dual chamber (air chamber) prevents outside noise from affecting the enclosure, essentially increasing bass response while the integrated ports enhance the efficiency of the driver. The housing (enclosure) is further reinforced by a 3-layer damping structure, suppressing vibrations and unwanted resonance, resulting in improved audio response out of the HD driver.
Large Housing and Comfortable Ear pads
The housing of the HRM-7 creates a large listening chamber to produce a wide sound field for better sound localization. Wrapped around the housings are full-sized hybrid memory foam ear pads, that feel extremely comfortable, even when worn for long periods of time. Furthermore, the memory foam ear pads are covered with soft velour that contours around the ears to help reduce exterior sounds entering the listening chamber.
Designed to Fit
The 3D ergonomic design further optimizes the angled fit of the ear pads around the head while the free adjust head cushion helps produce a snug fit across the entire head without creating uncomfortable force.
